The Gdańsk University of Technology was the first research organization in Poland that joined the international network for measuring the brightness of the Globe at Night – Sky Brightness Monitoring Network (GaN-MN). Measurements are performed using a specialized SQM-LE sensor by Unihedron, designed for long-term monitoring. The entire network includes 64 sensors located in 19 countries around the world.
The sensor was placed on the roof of Building B of the university campus. It allows scientists to measure the brightness of the sky continuously. Joining the network enables GUT scientists to access to data from all sensors in the GaN-MN network and increases the quality of research on artificial light pollution at night carried out by ILLUME – an interdisciplinary research group within the EcoTech research center at the Gdańsk university.
Scientists working in the group research the phenomenon of artificial light pollution and its negative impact on human health and the functioning of the natural environment.
